PIPE CLAMP AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 609,534, dated August 23, 1898. Application filed August 24, 1897. Serial lilo- 649,S68. (N0 model.)

To all whom, it may concern:

Be it known that I, ROBERT W. CLARK, a citizen of the United States, residing at Clinton, in the county of Big Stone and State of Minnesota, have invented certain new and useful Improvements in Pipe Clamps and Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is a stove-joint clamp and pipe-holder for chimneys, and is designed to prevent the joints of the pipe from separating from each other, and also to prevent the first joint of the pipe from separating from the chimney where it enters the same and to do away with the necessity of using wires, nails, or screws in the ceiling; and it consists in the novel construction and arrangement of its parts. My clamp may also be used for all other pipes and any two pieces of sheet metal.

In the accompanying drawings, Figure 1 is a perspective view of a stovepipe with my clamp attached thereto. Fig. 2 is a perspective view of the clamp. Fig. 3 is a longitudinal sectional view of a stovepipe, of the clamp, and of the holder, the thumb-screw, however, being in perspective. Fig. 4 is a sectional View of a' stove'pipe and of my clamp and of a holder securing the upper end of the pipe where it enters into the chimney just below the ceiling. Fig. 5 is a sectional view of a stove, of a stovepipe, of my clamp, and of my holder when the pipe enters into the chimney immediately opposite the stove.

Fig. 6 is a detailed sectional view showing sufiicient of my device to show the perforation in fold 6, flaring at its inner end and threaded at its outer end.

My invention is described as follows:

1 is a stovepipe consisting of several joints 7 and elbows, with my invention attached thereto. 2 is the clamp, consisting of a sheet of metal 3 folded back upon itself twice, the upper fold 4 having in its center a perforation, the middle fold 5 also having inits center a perforation, and the lower fold 6 having in its center a perforation flaring on the inner end and threaded on the outer end. Fold 6 is made rounded on the back, so as to make room for the threads. These perforations are adapted to register with each other. The three folds 4, 5, and 6 are held together by a thumb-screw 7.

In applying the clamp to the joint of the stovepipe the inner end, or that end (the smaller end of the stovepipe) that goes in the larger end of the next stovepipe, is thrust in between folds 5 and 6, and then the larger end of the stovepipe is thrust over the smaller end of its neighbor and between folds 4 and 5, and then a hole is made through the two stovepipes with the thumb-screw 7, adapted to register with each other and with the holes in the folds 4, 5, and 6. The thumb-screw 7 is then put in place and screwed down home tight. Thus the two joints are secured together so tightly that they cannot come apart.

My holder 12 consists of the body 13, having perforations 14, astraight arm 15, having on its end an elbow-crook or half arrow-head 16, and a spring-arm 17,-havin g on its extreme end an elbowcrook or half arrow-head 18. When I use my holder, I thrust the body 13 in the inside of the stovepipe and between the folds 4 and 5 until one of the perforations 14 comes immediately opposite to the perforations in the clamp, and then the joints of the stovepipe, the holder 12, and the clamp 2 are all secured together by the thumb-screw 7. The end of the stovepipe and holder 12 is thrust through the chimney until the elbow ends 16'and 18 fit against the inner face of the chimney-wall, thus holding the stovepipe in place either opposite the stove or that end of it which may enter the chimney immediately under the ceiling. Thus by using my clamp 2 and holder 12 all nails, screws, or other unsightly devices are done away with either in the wall, in the chimney, or in the ceiling above.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with a stovepipe, the clamp 2, thumb-screw 7, and a holder 12, having the perforated body 14 arm 15 with catch screw, rivet, or other substantial means, subend 16, and spring-arm 17, substantially as stantially as set forth.
